Description
Tungsten crucibles and other parts can be used for sapphire crystal growth and rare-earth melting due to their high-temperature resistance, low pollution, and other excellent characteristics. Tungsten’s melting point is 3422°C (6192°F), making it perfect as a crucible.
The tungsten crucibles manufactured through the chemical vapor deposition (CVD) process exhibit notable characteristics, including a high density reaching up to 98.5% of theoretical density, exceptional purity at 99.9999%, and a distinctive microstructure characterized by columnar or multilayer columnar crystals.
These tungsten crucibles find widespread applications in the production of monocrystals from molten corundum and play a vital role in electronics and thermal vaporization technologies for depositing various substances. Their high melting point is a key attribute of high-temperature furnaces.
Our tungsten crucibles are distinguished by their outstanding thickness transition, smooth surface, high purity, and robust resistance to creep, making them well-suited for demanding applications in high-temperature environments.
Applications of Tungsten Crucibles
Tungsten crucibles find versatile applications across various industries due to their unique properties. Here are some common applications of tungsten crucibles:
